<p>A hybrid coupler for UHF-band television transmission has a box (2) containing two lines (4), each of which is insulated from the box (2) and from the other line (4), is connected to the other line (4) in a "tandem" configuration, and has a first, a second, and a third portion (21, 22, 23) separate from one another and connected respectively to the third, second, and first portion (23, 22, 21) of the other line (4) to define a first, a second, and a third coupling section (34, 35, 36) to achieve a constant connection over the whole UHF band (470-862 MHz).</p> |
